Members of the CYP2 and CYP3A families play a significant role in the metabolism of many xenobiotics and endogenous compounds, including sex steroids.

In agreement with previous observations that CAR can bind to regulatory elements in CYP3A genes, CAR is also required for induction of expression of CYP3A11 in response to both PB and TCPOBOP in liver.
CAR is also required for the response of CYP2B10 to several additional xenobiotic inducers, including chlorpromazine, clotrimazole and dieldrin, but not dexamethasone, an agonist for both the xenobiotic receptor PXR (Pregnane X Receptor NR112) and the glucocorticoid receptor.

Furthermore, PXR and CAR induce enzymes, such as the CYP2B and CYP3A family members, responsible for the metabolism of steroid and thyroid hormones and this may alter their normal physiological function.
Environmental estrogens, such as the pesticides methoxychlor, endosulfan, dieldrin, DDT, and the plasticizer nonylphenol activate either PXR or both PXR and CAR.

The tested products fell into four major groups: a first group with pentachlorophenol, identified as a CYP3A inducer; a second group containing the methylcholanthrene-type inducers that increase CYP1A-related activities; a third class represented by dieldrin, a PB-type inducer; a fourth group including inert compounds or weak inducers.

In contrast, the chlorinated hydrocarbon pesticides, such as DDT, dieldrin, chlordane, and mirex, cause almost exclusively the induction of isoforms of the CYP2B (and to a lesser extent the CYP3A) subfamilies.
